Zusammenfassung: | The invention belongs to the technical field of efficient and safe production of mines, and discloses a coal and gas exploitation integrated permeability-increasing enhancer as well as a preparation method and application thereof. The coal and gas exploitation integrated permeability-increasing enhancer is composed of, by mass, 6%-10% of 20mol/l concentrated nitric acid, 1%-5% of N-lauroyl creatine sodium, 2%-6% of 1-butyl-3-methylimidazolium chloride and mine dustproof water. The coal and gas exploitation integrated enhancer provided by the invention can improve the wettability of a coal bodyby physicochemical modification of the coal body, inhibit and reduce the generation of dust in a coal seam exploitation process, greatly improve the permeability of the coal body, improve the coal seam occurrence and exploitation conditions, facilitate efficient development and utilization of coal seam gas, improve coal bed gas exploitation, relieve energy shortage, prevent gas disasters of underground coal mines, reduce |
